Abstract
Resumen. En este trabajo se estudió la nanofiltración de soluciones de glicina y triglicina mediante dos membranas NF–90 y MPF36. Dentro de las actividades realizadas se discuten las interacciones ocurridas entre las variables que afectan el proceso de nanofiltración, esto con el fin de aplicar el ajuste a los datos experimentales del modelo Spiegler–Kedem e identificar los fenómenos ocurridos. Al final de la investigación se pudo demostrar la relación entre el rechazo de las biomoléculas anfóteras y su dependencia con el pH. También se identificó que un aumento de la fuerza iónica de la solución de alimentación, disminuye el rechazo máximo de las biomoléculas utilizadas.

The activities discussed are the interactions occurring between the variables that affect the process of nanofiltration, this in order to apply the experimental data fit the model Spiegler–Kedem and identify phenomena occurred. At the end of the investigation was able to demonstrate the relationship between the rejection of amphoteric biomolecules and their dependence on pH. We also identified that increase the ionic strength of the feed solution decreases the maximum rejection of the biomolecules.
